For a strong acid - strong base titration, almost any indicator can be used, although phenolphthalein is most commonly employed. For titrations involving weak acids or bases, as in the acid titration of sodium carbonate solution shown here, the indicator should have a pK close to that of the...

In these subjects, they are often referred to as “acid-base reactions”, “acid-base titrations”, “ionic solutions”, and “acid-base theories”. We have identified four categories of rationales why students need to understand acid-base processes: daily life; socio-scientific; curriculum; ...

Moisture can only be measured by Karl Fischer titration. Using the elemental composition, thermal analysis data, and an XRD investigation, a probable composition for a calcium sulfate can be established. Like cements, the elemental composition is determined by XRF or AAS techniques. The XRF bead ...
